Question:
Is it possible to load a WordPress shortcode on demand, e.g. with a button?
Explanation:
I have a gallery plugin, it has a shortcode. Unfortunately, the plugin does NOT use image defer mechanism on page load. So it has too many image requests that hurt speed ranking.
Is this idea possible:
I want a "load gallery" button. When it's pressed, the gallery shortcode is loaded. Any recommendation / article / key concepts is welcomed. I don't even know where to start.
You can add custom buttons to the editor -> https://codex.wordpress.org/TinyMCE_Custom_Buttons
